Embodiment Construction

[0015] In the following description, the terms "top" and "bottom" refer to figure 2 sectional view of . The bottom is the hairspring side. Furthermore, the term "turned outward" is understood to mean facing in the opposite direction to the balance axis.

[0016] The accompanying drawing shows a sprung balance regulating part for a timepiece corresponding to a particular embodiment of the invention. figure 1 The balance wheel 7 is shown, the axis of which, ie the balance shaft, pivots between two bearings. In conventional manner, one of these bearings (designated 11) is carried by the balance bridge (or balance cock) 9 via the top balance end piece 13, while the other bearing is mounted in the main plate (not shown) . Also in a traditional manner, the balance is associated with balance spring 1 , the central end of which is attached to the balance shaft.

[0017] The pendulum bridge 9 also serves as a support for the assembly formed by the stud 3 , the stud holder 5 and t...

Abstract

The regulating device includes an inertial balance (7) including a balance staff arranged to be pivotally mounted in the timepiece, a balance bridge (9) and a bearing (11) carried by the balance bridge and arranged to hold one end of the balance staff, a balance spring (1) including an inner end integral with the balance and an outer end (1a) integral with a stud (3; 103), and a mechanism for securing the stud (3; 103) including a housing (17) for receiving the stud and which is formed in a stud holder (5) pivoted on the balance bridge (9), the securing mechanism further including an elastic arm (15; 115) arranged to pivot concentrically to the balance staff between a first position where the elastic arm immobilises the stud (3; 103) and a second position where the elastic arm is disengaged from the stud to allow the stud to be inserted into or removed from the housing.

Description

technical field [0001] The invention relates to a regulating device for a timepiece, said regulating device comprising a balance of inertia, a balance bridge, a balance spring and a mechanism for securing a stud, wherein said balance comprises a wheel arranged to be pivotally mounted on A balance shaft in a timepiece, said balance wheel bridge bridge carrying a bearing arranged to hold one end of the balance shaft, said hairspring comprising an inner end integral with the balance wheel and an outer stud (hereinafter referred to as "the outer stud") ) an integral outer end, said means for securing the stud comprises a housing cavity carried by the balance bridge and arranged to receive the stud while allowing longitudinal adjustment of the position of the stud, said fixing The mechanism also includes a resilient arm arranged to bear laterally against the stud so as to immobilize the stud against the wall of the housing cavity. Background technique [0002] A regulating membe...
